Research interests

My particular research interest is in the functional relationships between plants and their environment (particularly water and nutrients). I especially enjoy integrating experimental studies with field investigations to address research questions. I also am a keen communicator of science and environmental education.

Some recent projects I have been involved include:

  • Soil Moisture gradients and biodiversity in the Cape Flora, Western Cape, South Africa: looking at niche segregation, plant coexistence, ecohydrological management, evolution of plant diversity

  • Alternative valuing of Ecosystem Services for environmental management

  • Intergrating plant and soil micobial diversity in Iberian lowland and highland plant species assemblages, Northern Spain

  • Environmental education for the public and engagement in science, including Citizen Science on water, plants, hedges ...

  • Quantitative Ecology i.e. querying plant record databases for trends and also collaborating with statisticians to test new methods. Recent forays have been in Bayesian approaches.

Teaching interests

I have been an Associate Lecturer with the OU for a number of years, on various science, ecology and environmental science modules (from undergraduate to postgraduate) across faculties. I teach online, face-to-face and in the field, in addition to supporting research students. I particuarly enjoy modules that bridge across disciplines and involve approaches in technology-enhanced learning.

Some modules i have been involved are: Environmental Science (S206/SXF206), Biology of Survival (S295), Environmental Management (T219), Journey's in a changing Environment (U116), SXE390 (Science Project - Environment strand),  ...

I write public education blogs at OU's OpenLearn website.

External collaborations

I have active collaborations with colleagues in other institutions within the UK as well as overseas e.g. Spain, Germany and South Africa.
